Who uses a stock news API
MarketNewsAPI is the news layer for event-driven traders, long-term investors, bots, dashboards, agents, and desks. Each guide names the audience, the filters they call, and what comes back.
What is a stock news API used for?
Developers and investors use MarketNewsAPI to search and stream US stock news, press releases, and legal notices. Every article includes tickers, a short summary, and a link to the source. One Pro plan covers REST, WebSocket, and MCP at $15 a month.
Search it
REST is for a watchlist, a backtest, a dashboard, or a newsletter. Filter by ticker, type, source, and date. Free can prove the query: 100 requests a day, delayed 15 minutes.
Stream it
The WebSocket is for a bot or a live desk. Pro, including the 7-day trial, pushes articles as they are ingested. Free does not include the socket.
Hand it to an agent
MCP gives Claude, ChatGPT, Cursor, and your own agent the same articles as tools. Pro includes it. A card is required for the trial.
